When rotor is at standstill?
slip is zero
The common problems associated with the steam turbine include high vibration due to deposition on rotor blades, errosion of casing due to steam condensation at low pressure zone, breakage of blades from roots due to resonance, efficiency loss due to increaed internal clearnaces, high axial displacement & thrust bearing demage due to balance piston labyrinth leakage & rotor bow while turbine is standstill at high temperature.
A transformers main function is to change one voltage to another voltage. A motors main function is to relieve man of tedious and repetitive work and also work that man has not the strength to do alone. Another Answer Although, as outlined in the first answer, they have completely different functions transformers and induction motors do in fact have certain similarities. They each have a primary winding and a secondary winding (although, in the case…
Why will the rotor of a wound-rotor motor not turn if the rotor circuit is left open with no resistance connected to it?
To access the rotor, remove the tire and brake caliper. There will be a cap protecting the bolt that holds the rotor onto the spindle. Removing the cap, located in the center of the rotor (on the spindle, not the rotor itself) will allow you to get access to the bolt. Removing that bolt frees the rotor from the spindle.
